问题描述

我使用QMainWindow为我的项目的GUI开发。我遇到的一个问题是阻止所有其他可见窗口获取输入,而一个正在操作。



我如何声明一个特定的窗口为模态?



我尝试使用 QWidget :: setWindowMOdality()



  #include< QApplication> 
#include< QMainWindow>
#include< QPushButton>




int main(int argc,char ** argv){


QApplication a(argc,argv );


QMainWindow * w1 = new QMainWindow();
w1-> resize(500,800);
w1-> move(100,50);
w1-> show();


QMainWindow * w2 = new QMainWindow();
w2-> resize(800,500);
w2-> move(50,50);
w2-> show();

w2-> setWindowModality(Qt :: ApplicationModal);


return a.exec();

}


解决方案
  w2-> setWindowModality(Qt :: ApplicationModal) 
w2-> show();

也可以使用QWidget并建立工具栏,菜单栏和状态栏。


I am using QMainWindow for GUI development of my project..One problem I am Stuck with is blocking all other visible windows from getting input, while one is in operation.

I can not use QDialog.Because rich features of QMainWindow is required.

How can I declare a particular window as modal?

I tried with QWidget::setWindowMOdality().

Here is a demo program, what I tried but it didnt work.

#include <QApplication>
#include <QMainWindow>
#include <QPushButton>




int main(int argc, char **argv){


QApplication a(argc, argv);


    QMainWindow *w1 = new QMainWindow();
    w1->resize(500,800);
    w1->move(100,50);
    w1->show();


    QMainWindow *w2= new QMainWindow();
    w2->resize(800,500);
    w2->move(50,50);
    w2->show();

    w2->setWindowModality(Qt::ApplicationModal);


    return a.exec();

}
解决方案

Try setting the modal flag first, then show the widget.

w2->setWindowModality(Qt::ApplicationModal);
w2->show();

Also you could use QWidget and build the toolbar, menu bar and status bar.
